| Background Antimicrobial resistance resulted in international accordance to strengthen the research to investigate novel treatment options including medicinal plants. To investigate the effect of two dosages of an orally hydro-ethanolic Echinacea purpurea (L.) MOENCH spissum extract (EP) on performance, clinical health, antibody production, red and white blood cell count and expression of immunological parameters in calves, a double-blinded placebo-controlled clinical trial has been performed. |

| Two different methods to reveal body condition scores (BCS), called independent BCS (iBCS) and dependent BCS (dBCS; similar to the method of Ferguson et al. 1994), were applied in 1111 Swiss Brown dairy cows. Ultrasound measurement of the back fat thickness (BFT) served as validation method. Aim of the study was to evaluate the impact of assessor’s subjective impression of the overall appearance of the cow on the scoring process. With 67.3% of the BFT variance, the dBCS with its consideration of the overall impression of the cow and its more open approach was more suitable to predict the subcutaneous fat appositions. The strictly formularized iBCS could only explain 47.3% of the BFT variance. The pin bone region was identified to cause the biggest... |

| In order to test the effect of organic vs. conventional diets on fertility traits, we conducted an on-farm study with female rabbits. Eight groups of seven to eight female rabbits kept in systems with litter were fed ad libitum with either organic or conventional pellets. Offspring was weaned with approx. 28 days. In the first series analysed, the conception rate was higher in the conventional groups. Diet type had no significant influence on that trait. Nevertheless, a significant influence of diet on litter size was found: organically fed female rabbits produced more offspring per litter. The organic groups also showed higher rates of weaned animals, despite of a slightly higher mortality of offspring in these groups, but differences for both... |

| This study investigated the effect of, and interactions between, US Brown Swiss (BS) genetics and season on milk yield, basic composition and fatty acid profiles, from cows on low-input farms in Switzerland. Milk samples (n = 1,976) were collected from 1,220 crossbreed cows with differing proportions of BS, Braunvieh and Original Braunvieh genetics on 40 farms during winter-housing and summer-grazing. Cows with more BS genetics produced more milk in winter but not in summer, possibly because of underfeeding potentially high-yielding cows on low-input pasture-based diets. Cows with more Original Braunvieh genetics produced milk with more (i) nutritionally desirable eicosapentaenoic and docosapentaenoic acids, throughout the year, and (ii) vaccenic and... |

| Our aim was to map the performance of local (native) dairy cattle breeds in Austria, Switzerland, Poland, and Sweden with regard to production, fertility, longevity, and health-associated traits and to compare them with commercial (modern) breeds. For this purpose, we analyzed test-day records (July 1, 2011, to June 30, 2014) and treatment records (Austria, Sweden) of cows managed on organic farms. We performed country-wise comparisons of 123,415 lactations from Original Braunvieh (OB) and Grey Cattle (AL) with Braunvieh (BV; Brown Swiss blood >60%) in Switzerland; AL with BV (Brown Swiss blood >50%) in Austria; Polish Black and White (ZB), Polish Red and White (ZR), and Polish Red (RP) with Polish Holstein Friesian (PHF) in Poland; and Swedish Red... |

| Der biologische Landbau ist weltweit ein Wachstumsmarkt. Die Länder Süd- und Osteuropas haben ein gutes Potential für ein Wachstum im Biosektors. Ein wichtiger Einflussfaktor hierbei ist das Vorhandensein des nötigen Fachwissens vor Ort. Ziel des hier vorgestellten dreijährigen Projektes war es daher, die Lehre zum biologischen Landbau an den beteiligen Agrarfakultäten in Albanien, Bosnien und Herzegowina, Kosovo, Bulgarien und Ungarn durch die Förderung von Wissenstransfer und die Einführung von e-learning Instrumenten nachhaltig zu verbessern. Wesentliche Projektergebnisse sind die Erstellung einer Grundlagenvorlesung zum Biolandbau auf BSc. Niveau, die Einführung eines e-learning Instruments und die Sicherung einer nachhaltigen Verfügbarkeit der... |

| Die Biolandbau-Richtlinien empfehlen die Verwendung lokal angepasster Nutztierrassen. Es existieren bisher jedoch kaum Studien zur Eignung lokaler Milchviehrassen unter den Bedingungen des Biolandbaus. Lokal angepasste Milchviehrassen könnten besser an die Bedingungen des Biolandbaus angepasst sein als kommerzielle Rassen, da ihre Leistung auf die lokale Futtergrundlage und graslandbasierte Fütterungssysteme abgestimmt ist. Auf dem Poster werden die Ergebnisse des Vergleichs von Braunviehkühen mit einem Brown Swiss Blutanteil von mind. 60% als kommerzielle Rasse mit den zwei lokalen Rassen Original Braunvieh und Grauvieh auf Schweizer Biobetrieben gezeigt. |

| Im biologischen Landbau spielt das Rind auf Grund seiner Veredelungsfunktion für Grünlandressourcen und auf Grund seines hochwertigen Düngers eine besondere Rolle. Allein in Deutschland werden auf 20%, in der Schweiz gar auf knapp 40% der Biobetriebe Milchkühe gehalten. Wegen ihrer niedrigeren durchschnittlichen Milchleistungen sowie des starken Einsatzes von Grundfutter wird die Umweltwirkung der Bio-Milchrindhaltung aktuell verstärkt kritisch diskutiert. Wissenschaftliche Vergleiche von konventionellen und biologischen Milchviehsystemen in Hinblick auf ihre Umweltwirkung haben jedoch je nach Einbeziehung unterschiedlicher Einflussgrößen und variierender Definitionen von Systemgrenzen zu uneinheitlichen Ergebnissen geführt. Nach kurzen Impulsreferaten... |

| Die lokale Rasse Anglerrind alter Zuchtrichtung (AAZ) wurde in Bezug auf Gesundheit, Fruchtbarkeit und Leistung mit der weitverbreiteten Rasse Holstein (HO) verglichen. Milchleistungsprüfungsdaten vom 1.7.2011 bis 30.6.2015 wurden von 340 AAZ-Kühe auf sieben Biobetrieben mit einer Kontrollgruppe von 690 HO-Kühen auf 13 Betrieben verglichen. Die HO-Betriebe wiesen ein vergleichbar extensives Management auf wie die AAZ-Betriebe, um Umwelteffekte zu minimieren. Der Gesundheits- und Fruchtbarkeitsstatus war für AAZ- und HO-Kühe auf einem ähnlichen Niveau, jedoch zeigten AAZ-Kühe ein geringeres Risiko für subklinische Azidose, hatten tendenziell weniger Euterbehandlungen und wiesen tendenziell eine geringere Güstzeit auf. Die Milchleistung der AAZ-Kühe war nur... |

| The accuracy of genomic prediction determines response to selection. It has been hypothesized that accuracy of genomic breeding values can be increased by a higher density of variants. We used imputed whole-genome sequence data and various single nucleotide polymorphism (SNP) selection criteria to estimate genomic breeding values in Brown Swiss cattle. The extreme scenarios were 50K SNP chip data and whole-genome sequence data with intermediate scenarios using linkage disequilibrium-pruned whole-genome sequence variants, only variants predicted to be missense, or the top 50K variants from genome-wide association studies. We estimated genomic breeding values for 3 traits (somatic cell score, nonreturn rate in heifers, and stature) and found differences in... |

| Postweaning diarrhoea (PWD) due to Escherichia coli is an economically important disease in pig production. In this placebo-controlled study performed in Switzerland, the effects of oral supplementation of Allium sativum L. (garlic, AS) on performance (bodyweight (BW) and daily weight gain (DWG)) and health (body condition and clinical score) were investigated in postweaning piglets. Piglets (n=600) were randomly assigned to the treatment groups (placebo, AS or colistin) and observed from birth until three weeks postweaning. The treatments were administered for the first two weeks postweaning. Faecal dry matter (FDM) and coliform bacteria on pen level were measured weekly. Data were analysed using generalised mixed-effect models in R. BW and DWG of the AS... |

| Stature is affected by many polymorphisms of small effect in humans1. In contrast, variation in dogs, even within breeds, has been suggested to be largely due to variants in a small number of genes2,3. Here we use data from cattle to compare the genetic architecture of stature to those in humans and dogs. We conducted a meta-analysis for stature using 58,265 cattle from 17 populations with 25.4 million imputed whole-genome sequence variants. Results showed that the genetic architecture of stature in cattle is similar to that in humans, as the lead variants in 163 significantly associated genomic regions (P < 5 × 10−8) explained at most 13.8% of the phenotypic variance. Most of these variants were noncoding, including variants that were also expression... |
